BEAM-I-IANGElR Application filed September This invention relates to a well pumping device wherein awalking beam is connected to the rods of a reciprocating well. pump. It pertains particularly to a safety device for holding a pump rod in case of breaking of the hanger or parts operatively securing the beam to the polish rod or equivalent portion of the pump string.

It is the primary object of this invention to provide a device of the character described which is simple, economical, durable, does not interfere with the operation of the equipment or require changes in the standard equipment now used.

These ob 'ects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Fig. 1 shows in vertical section my improved hanger construction mounted on the end of a walking beam, a fragment of the latter being shown; and Fig. 2 is a view oi the structure shown in Fig. 1.

Referring particularly to the drawing, 3 indicates a walking beam which is slotted at the end as indicated by 4:, through which slot the stem of a beam hanger may pass. Mounted in a suitable groove extending transversely across the top of the beam is a crown having a cross head 5 provided with an arcuate upper guide 6 overhanging the beam for receiving a cable or like flexible line.

A stem 7 depends from the cross head, and at the lower end thereof is a supporting guide 8 of arcuate form for receiving a cable. The polished rod forming a portion of the pump string is indicated by 9 and mounted thereon is a clamp or grip 10. The grip is provided with trunnions on opposite sides, and socket eyes 12 are pivotally mounted thereon. Passed over the guide head 8 and secured to the socket is a cable 13. This cable is intended to couple the polished rod to the beam and to be the operating means for reciprocating the polished rod.

Extending beneath the grip 10 is a safety cross bar let having trunnions 15. at the ends thereof. Pivotally mounted upon the trunnions 15 are eye sockets 16 to which a cable -17 is secured. Cable 17 is passed over guide 6. This cable with associated Parts is in tended to catch the polished rod in the event that the hanger stem or cable breaks. The operation of the structure is obvious.
